1 前言环境应力筛选(以下简称ESS)是80年代在美国军事工业界兴起的热门技术,80年代末期引入我国军工系统,作为一种工艺手段,它通过向元器件(组件)、分机、整机等施加各种环境应力(包括电应力),使隐藏的潜在缺陷迅速发展为可检测的故障,并随即采取措施消除这些潜在的缺陷。 1 Introduction Environmental stress screening (hereinafter referred to as ESS) is a popular technology that emerged in the U.S. military industry in the 1980s. It was introduced into China’s military system in the late 1980s as a process measure. Through the introduction of components (components), extensions, And other environmental stress (including electrical stress), the hidden potential defects quickly developed into detectable failure, and then take measures to eliminate these potential defects.
